I Patented Nov. 4, 1930 units 3303 WITH, or SKOYEN, NEAR osto, NORWAY Application filed March IG; 1929, Serial No. a i'ntrz jaiid in No inat 192 8;

The present invention relates to ski ties of the type which have toe irons that aresecured to the upper side ofthe ski, one of the said toe irons being provided with a projection or projections which engage into a slot or cut-out portion or portions in the other toe iron.

It is the object of my inventionto provide a ski tie of the above mentioned type which may be easily and accurately positioned and secured in adjusted position on the ski.

In the drawing Figs. 1 and 2 illustrate two diiferent'embodiments of a ski tie according to my invention in plan View.

"Fig. 3 shows a section along the line III III in Fig. 2 and Fig. 4 shows a detail in perspective.

In the drawing 1 is a portion of the ski proper, and 2 and 3 designates the toe irons.

which are secured to the ski 1 by means of securing screws 4.

According to Fig. 1 the toe 1ron 3 is provided with a projection 5 which extends into a cut-out6 in the other toe iron 2 in such manner that an opening is formed between one side edge 7 of the projection 5 and the side edge 8 of the cut-out, both of which edges 7 and 8 respectively are bevelled as indicated in Fig. 1. Saidyopening preferably extends in a direction at right angles to the longitudinal direction of the ski 1 and receives an adjusting screw 9 as described more fully below. The other side edge 10 of the projection 5 engages the side edge 11 of the portion 12 of the toe iron 2 which forms the foremost limit of the cut-out 6. In order that the toe irons may be relatively turned somewhat during the adjusting operation, said edge 10 is arcuated, as shown. The portion 12 is relatively narrow and by means of a slot 19 it may be given relatively great length in order to become somewhat resilient in the longitudinal'direction of the ski. i

In Fig. 2 is illustrated an embodiment in which both toe irons 2 and 3 are provided with a projection 13, between the adjacent bevelled side edges 13 of which the adjusting screw 9 is received.

Between that side edge ofeachof the projections which is not engaged by the screw 9 and-the adjacent side edge of the cut-out in theother toe iron may be placed narrow intermediate members about which the toe irons may be turned somewhatwhen the toe irons are adjusted in position upon the ski. As indicated in Figs. 2" and 1 said intermediate members may be formed by'the upwardly bent ends 1 1 of a n'1ernber16 which is placed below the projections 13 and sunk into the upper surface of the ski; The member 16 then at itsmiddle portionis provided with an opening 15 through which the screw 9 is passedi Instead of using "the. said intermediate members the side edges of each of the pr'oj tions might also be rounded-and engage the edge of thecut-out, in a way similar to that indicated at 10, 1 1, 12in 1.

As indicated 'nthe sectional view inFig. 3

the horizontalportions of the toe irons may be slightlyrarched or'curved, preferably in the longitudinal direction of th'e ski.

' When the toe .ironsare to be mounted and adjusted upon a" ski',"the point where the screw 9 'is to be placed is at first marked upon the ski, and said screw 9 is then screwed into the ski to a suitable depth. Then the toe irons are passed with their edges 7 or 13 respectivelyhin under the head. of the screw 9 and the latter is tightened somewhat more, so that f it presses the toe irons against the ski with a suitable pressure, due to the resiliency of thehori-Zontal portions of the toe irons. i v

Thus the toe irons are temporarily secured, and they'maynow be accurately adjusted in the-desired positions on the ski, both as regards the distance between the vertical portions ofthe toe irons and the inclination 7 thereof in relationto the longitudinal direc tion of. the ski. Duringsuch adjustment the adjusting screw 9 will cause suflicient friction between the toe irons and the ski, so that the toe irons will not be; displaced. When the toe irons have been accuratelycadjusted in the desired position thesecuring screws 4 are inserted and tightened, so that the horizontal, arched portions of the toe irons are pressed entirely down on to the surface of the ski.

j -Having now particularly described and,

ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. Toe irons for a ski tie comprising horizontal portions adapted to be secured to the upper surface of the ski, one of which portions is provided with a projection received by acut-out in the other portion, one side edge ofthe projection and the adjacent side edge of the cut-out being beveled, such side edges being so far apart that a slot isformed therebetween, an adjusting screw entering the slot and acting against the beveled portions of said edges and forcing the opposite edge of the projection against the adjacent side edge of the cut-out and thereby temporarily securing said portions to each other and to the ski under the adjustment of said irons.

2. Toe irons for a ski tie comprising horizontal portions adapted to be secured to the upper surface of the skiyeach portion being provided with a projection and a V cut-out adapted to receive the projection of the other portion in such manner that a slot for an ad- I justing screw is formed between adjacent edges of the projections, said edges being beveled in order that the adjusting screw may actagainst said beveled edges and force the so opposite edges of said projections against the adjacent edges of the cut-outs and thereby temporarily securing said portions to each other and to the ski under the adjustment of said irons.

3. A toe iron as claimed in claim 1, in which the portion of the toe iron limiting the cut-out is resilient in the longitudinal direction of theski.

4. A toe iron as claimed in claim 2, in which the portion of the toe iron limiting the cutout is resilient in the longitudinal direction of the ski.

5. A toe iron as claimedin claim 1, having a narrow portion limiting the cut-out atone side thereof, said portion being extended by the arrangement of a slot extending sideWise in the horizontal portion of the toe iron.

6. Toe irons as claimed in claim 1, in which the side edge of the projection which engages one side edge of the cut-out is curved.
